Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E. e. eschscholtzii?

E.e. oregonesis

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
